Nobody can deny that 2014 was a great year for mobile: according to Flurry, mobile usage grew 76% year-over-year in 2014. Messaging apps had their year of fame in 2013, but in 2014, it was shopping and other retail-oriented apps that really took off.Now shopping apps aren’t just for individual consumers. If your business takes advantage of the perks and rewards gained through these apps, you can save your company a lot of money and time in 2015!So without further ado, here are our three favorite retail apps you should use for your small- or medium-sized business:1. ClutchKeep all of your loyalty card data within your smartphone. Whenever you make a business purchase out, just flash your phone at checkout and get your discount instantly! Plus, you can take advantage of Clutch’s loyalty program to earn points toward gift cards.2. Staples AdvantageThe app for all of your business supply ordering needs! One-touch ordering makes it super easy to order all the paperclips, toner, and pens you need. One small catch: Your business must employ at least 20 people, so if you’re a microbusiness you’ll want to use the original Staples app instead.3.
